Figure 1. Positions obtained by only Galileo E1 Open Service (the antenna is located at the roof of the Ta Quang Buu library building inside HUST campus)

Scientists in Hanoi, Vietnam, send word that on March 27 the four Galileo in-orbit validation satellites were visible at the same time in the sky over that Southeast Asian country for nearly two hours (from 2:15 to 4:00 GMT) while transmitting a valid navigation message. The research team of the NAVIS Centre at Hanoi University of Science and Technology (HUST)... read more

Making Europe’s Seaways Safe for eNavigation

28 days worth of ship-traffic data for the Strait of Dover.

An overview of the work of the General Lighthouse Authorities of the United Kingdom and Ireland on the implementation of Enhanced Loran Initial Operational Capability (IOC) in the waters around Great Britain. eLoran is the latest in the longstanding and proven series of low-frequency, LOng-RAnge Navigation systems. It evolved from Loran-C in response to the 2001 Volpe Report on GPS vulnerability. It vastly improves upon previous Loran systems with updated equipment, signals, and operating procedures. read more

Out in Front: Galileo’s World

GalileosWorldCovers-O

It’s been a long time coming. With the capability to make a position fix from four signal-broadcasting satellites, we can now say that Galileo has truly arrived. Of course, this is only one of many milestones (excuse me, kilometer markers) along the way, a trajectory that could be bounded at 23 years and counting, or possibly longer. Let’s not forget,... read more

EGNOS and Galileo Track Dangerous Goods

April 1, 2013By
EGNOS-Opener

EGNOS availability over Europe, as a precursor of Galileo globally, provides a guaranteed level of positioning accuracy in real time, for tracking vehicles transporting hazardous material. The EGNOS Open Service enhances position accuracy compared to GPS-only. The EGNOS Data Access Service further enhances accuracy and indicates the quality of the position data received from GPS. As a result of the SCUTUM project, EGNOS is now used in the operational transport of dangerous goods by road in Europe. read more

Expert Advice: Setting Standards for Indoor Position

April 1, 2013By

Communications Security, Reliability, and Interoperability Council (CSRIC) Update By Greg Turetsky Many of us remember way back in 2001 when the FCC first announced E911 position reporting requirements for cell phones. That was a long time ago in many significant ways. Everyone had 2G phones and anxiously anticipated the arrival of 3G, and with it, data. Most people still had... read more
